My brother was doing a tune up on his 300 and decided to adjust the air/fuel with no prior experience to this task and has totally screwed it up to the point it will barely run. He'll be bringing it to me this week to pull and clean the carb among other things for a small fee of liquid brew ha ha. It's been many years since I've owned a honda and can't remember where the carb A/F should be set for a starting point. If I remember right it was 1 3/4 turn out from seated position for many of them. Can someone confirm this?

OH! And I didn't have to lecture him about messing with things he knows nothing about. His wife already ripped him with the, you can't just leave things alone and now you broke it! Go call your brother to fix it and leave s#!t alone! LMAO!!! But he gets an A for effort I guess?
